Liquid discharge apparatus

Abstract

A liquid discharge apparatus includes a transport path that is configured to transport a medium in a transport direction, a liquid discharge head that discharges a liquid to the medium transported in the transport direction, a carriage that is configured to move the liquid discharge head in a width direction intersecting with the transport direction, a cover member that is located above the carriage and covers a movement range of the carriage, and an air flow adjustment cover that is located between the cover member and the carriage and covers the movement range of the carriage.

What is claimed is:

 a cover member that is located above the carriage and covers a movement range of the carriage; and 
 an air flow adjustment cover that is located between the cover member and the carriage, covers the movement range of the carriage, and suppresses the generation of airflow between the carriage and the cover member. 
 
     
     
       2. The liquid discharge apparatus according to  claim 1 , further comprising:
 an external case that has a box shape; and 
 an apparatus main body that is provided in the external case and configured to be drawn out and to which the carriage is attached, wherein 
 the cover member forms a part of the external case, and 
 the air flow adjustment cover is attached to the apparatus main body. 
 
     
     
       3. The liquid discharge apparatus according to  claim 1 , further comprising
 a carriage frame to which the carriage is movably attached, wherein 
 the air flow adjustment cover is attached to the carriage frame. 
 
     
     
       4. The liquid discharge apparatus according to  claim 3 , wherein
 the air flow adjustment cover is rotatably attached to the carriage frame, and 
 is configured to be located at an air flow adjustment position where the air flow adjustment cover covers the movement range of the carriage and a retreat position where the air flow adjustment cover is retreated from the air flow adjustment position and exposes the carriage and the transport path. 
 
     
     
       5. The liquid discharge apparatus according to  claim 3 , wherein
 the air flow adjustment cover includes 
 a first cover that is attached to the carriage frame, and 
 a second cover that is rotatably attached to a tip end of the first cover, and 
 the second cover is configured to be located at an air flow adjustment position where the second cover covers the movement range of the carriage and a retreat position where the second cover is retreated from the air flow adjustment position and exposes the carriage and the transport path. 
 
     
     
       6. The liquid discharge apparatus according to  claim 5 , wherein
 the second cover includes an operation knob for rotating operation, and 
 the operation knob has, at a tip end, a mounting portion that is mounted on a mounted portion provided in another member to determine the air flow adjustment position of the second cover. 
 
     
     
       7. The liquid discharge apparatus according to  claim 5 , wherein at least the second cover of the air flow adjustment cover has a plane surface facing the carriage and an opposite surface on which a reinforcing rib is formed. 
     
     
       8. The liquid discharge apparatus according to  claim 1 , wherein a distance from the air flow adjustment cover to the carriage is adjustable. 
     
     
       9. The liquid discharge apparatus according to  claim 1 , further comprising:
 an external case that has a box shape; and 
 an apparatus main body that is provided in the external case and configured to be drawn out and to which the carriage is attached. 
 
     
     
       10. The liquid discharge apparatus according to  claim 1 , further comprising:
 an apparatus main body configured to which the carriage is attached, wherein 
 the cover member is located above the apparatus main body, and 
 the air flow adjustment cover is attached to the apparatus main body. 
 
     
     
       11. The liquid discharge apparatus according to  claim 10 , further comprising:
 an external case that has a box shape, 
 wherein the apparatus main body is provided in the external case and configured to be drawn out. 
 
     
     
       12. A liquid discharge apparatus comprising:
 a transport path that is configured to transport a medium in a transport direction; 
 a liquid discharge head that discharges a liquid to the medium transported in the transport direction; 
 a carriage that is configured to move the liquid discharge head in a width direction intersecting with the transport direction; 
 a cover member that is located above the carriage and covers a movement range of the carriage; 
 an air flow adjustment cover that is located between the cover member and the carriage and covers the movement range of the carriage; and 
 a carriage frame to which the carriage is movably attached, wherein 
 the air flow adjustment cover is attached to the carriage frame, 
 the air flow adjustment cover is rotatably attached to the carriage frame, and 
 is configured to be located at an air flow adjustment position where the air flow adjustment cover covers the movement range of the carriage and a retreat position where the air flow adjustment cover is retreated from the air flow adjustment position and exposes the carriage and the transport path. 
 
     
     
       13. A liquid discharge apparatus comprising:
 a transport path that is configured to transport a medium in a transport direction; 
 a liquid discharge head that discharges a liquid to the medium transported in the transport direction; 
 a carriage that is configured to move the liquid discharge head in a width direction intersecting with the transport direction; 
 a cover member that is located above the carriage and covers a movement range of the carriage; 
 an air flow adjustment cover that is located between the cover member and the carriage and covers the movement range of the carriage; and 
 a carriage frame to which the carriage is movably attached, wherein
